What is research-based design?
Student and teacher materials are developed using an iterative process, which involves development, piloting, and field-testing phases. Data and feedback are collected during piloting and field-testing. These data are used to inform the revisions to the program.
Initial Program Development
Science education research provides the research background for our pedagogical approach. National standards and customer desires are taken into account. Lesson sequences are tried out in local schools by project staff, to create a version suitable for national testing.
Field Tested Across the Country
Initial drafts and equipment prototypes are tested in a diverse array of classrooms across the country—urban, suburban, and rural. Data on student performance is collected to inform the redevelopment process.

Reviews by leading scientists working in the specific field of each unit make sure our materials (cover to cover) are scientifically accurate and reflect up-to-date scientific knowledge and research.
